@Ashok: There are several Struts 2 books already, but it's nice to be in the mix
The table of contents was recently changed (primarily re-ordering of chapters) but includes chapters on: S2 actions, S2 results, S2 interceptors, S2 validation, OGNL, Custom tags, Form tags, Exception Handling, Two JavaScript chapters (including the DOM and CSS), S2 Themes and Templates, RIA,
Testing, and Documentation.
@Shahzad: I'm not sure I understand the question; it's a Struts 2 book that focuses on Struts 2.1.
